WICK-TUBE FOR LAMP AND STOVE BURNERS.

SPECIFICATION forming part of Letters Patent No. 234,706, dated November23, 1880.

Application filed August 31, 1880.

To all whom tt may concern Be it known that I, NICHOLAS GnoTsnN- BURG,of Janesville, in the county of Rock and State of Wisconsin, haveinvented a certain new and useful Improvement in IVic-k- Tubes for Lampand Stove Burners, of which the following is a specifiction.

The object I have in view is to prevent the heat from the flame of alamp or stove burner from passing to any considerable extent down thesides of the wick-tube and heating the lamp-collar or the oil-reservoir.This I accomplish by providing the wick-tube with peculiar slots in itssides, which cut off the downward current of heat without destroying thesubstantial continuity of the sides of such wicktube or exposing thewick.

In the accompanying drawings, forming a part hereof, Figure .1 is a sideelevation of a wick-tube embodying my invention; Fig. 2, a verticalsection of the same at right angles thereto, and Fig. 3 a horizontalsection through the lower edges of the slots.

A is a wick-tube, which is shown as a broad tube, such as is used inoil-stoves, but, as before stated, it may be the wick-tube of alampburner. The wick-tube is provided with the usual stem and wheels foradjusting the wick.

Below the wick-adjusting devices the tube (No model.)

has two slots, B B, located opposite each other 0 in the sides of thetube and extending; nearly across such sides, sufficient metal onlybeing left at the edges 0 a of thetube to give it the required strength.The slots B B are formed before the parts of the tube are secured to- 35 gether by separating the metal at the lower edges of the slots andbending the upper edges, 1) b, of the slots outwardly, as shown in Fig.2. This outward flare is given at the same time that the slots are out.By constructing the 40 slots in this manner the edges of the metal areseparated, so that the downward current of heat is in a great measurecut off, and at the same time the wick is not exposed so that itcancollect dirt or come in contact with any 5 object at those points thesubstantial continuity of the sides of the wick-tube not beingdestroyed.

hat I claim as my invention is The wiclctube A, having long slots 13 Bin 50 its sides, provided with flared upper edges, 1) b, substantiallyas and for the purpose set forth.

NICHOLAS OROTSENBURG.
